PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PILE FABRIC.

Specification of Letters Patent.

Patented Dec. 1'7, 1907.

Application filed November 2, 1906. Serial No. 341.758.

.T 0 all whom it may concern:

Be it known that I, HARRY HARDWIOK, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Pile Fabrics, of which the following is a specification.

The object of my invention is to so weave a pile fabric as to providefor a close disposition of the pile loops or tufts together with a morevaried coloring of the pattern than can be effected in pile fabricswoven in accordance with the methods now used.

In the accompanying drawings :-Figures 1, 2 and 3 are views of adiagrammatic character showing the different sheddings of the warpthreads resorted to in weaving pile fabrics in accordance with myinvention; Fig. 4 is an enlarged transverse section, partly on the linea-a, Fig. l, and partly on the line c-c, Fig. 1, and Fig. 5 is anenlarged transverse section on the line b b, Fig. 1.

My invention relates to that class of pile fabrics in which the pileforming warp is composed of sets of threads repeated as often as may benecessary to producev a fabric of the desired Width, each set comprisinga number of threadsof difierent colors, and alternating with a pair orset (hereinafter, for convenience, termed a set) of binding warpthreads, the latter being interwoven with suitable weft threads, WhlGllserve to confine the pile warp' threads and form, with the same and thebinding warp threads, a backing fabric from which the pile loops ortufts project.

In weaving such fabrics it is customary to raise one pile-forming warpthread of each set for the insertion of the pile wire, these threadsbeing then depressed to form loops around said wire, and the fine warpthreads being operated -to form a shed. or sheds for the insertion ofthe binding weft threads above and below the pile warp threads.

The number of pileforming warp threads in a set does not usually exceedfive, and the color range of the pattern is correspondingly limited.

In carryin out my invention, I raise a plurality of t e pile warpthreads from each set throughout the fabric, or throughout any selectedportion of the same, for the insertion, of a pile wire, and, as aconsequence, there are, wherever such operation takes place, a

plurality of pile loopsor tufts between ading web 0 joining sets ofbinding warp threads. This 'inultiplication of the number of loops ortufts enables me to produce a sufficlently close pile with the use offine yarns, and I can therefore use more pile threads in a set -than isthe present practice, and can accordin ,ly enlarge to a correspondingextent the co or range of the pattern.

In the drawings, 1 represents art of the swinging lay of the l'oom, 2the s uttle race,

'3 the reed, 4 thedifferent pile-forming warp threads, 5 and 6 the tyingor binding warp threads, 7 the pile Wires, 8 and.9,.respectively, theupper and lower binding weft threads, 10 the harness cords controllingthe pile-forming warp threads, 11 and 12 the eddles controlling thebinding warp threads,

and 8 and 9 respectively, the shuttles for introducing the .upper andlower binding weft threads 8 and 9.

Both of the binding weft threads are, in the present instance, containedin the same shed of binding warp threads, but any desired number ofbinding warp threads and Weft threads may be employed, and'these maybeinterwoven in difierent ways, and one or more stufi'er warp threads maybe employed in the ordinary way in connection with each set ofpile-forming warp threads, these features of the fabric forming noessential part of my invention, which relates to the manner of sheddingthe pile-forming warp threads for the insertion of the pile wires, andto the disposition of these threads in respect to the binding warpthreads of the fabric.

In the present instance I have shown each set of pile-forming wa threadsas consisting of eight threads of di erent colors, but eac set may, ifdesired, contain a plurality of threads of the same color and instead ofshedding these threads in pairs, as shown, a greater number of threadsof each set may be simultaneously lifted for the insertion of the pilewire, due regard, of course, being always maintained for the confinementof the binding weft threads 8 and 9 so closely as to insure the tying ofthe pile-forming loops or tufts firmly into the backing fabric.

Each of the pile threads is composed of a plurality of strands or ends,in order to insure the spread of the pile loops or tufts, necessary toroperly cover and hide the backf the fabric as shown in Fig. 1.
